Ependymal Cells [edit]. The ependyma is made up of ependymal cells, ependymocytes, a type of glial cell. These cells line the CSF-filled ventricles in the brain and the central canal of the spinal cord. The cells are ciliated simple columnar epithelium-like cells.heir apical surfaces are also covered with microvilli, which absorb CSF. Ependymal cells also produce CSF. Within the ventricles of the brain, a population of modified ependymal cells and capillaries together form a system called the choroid plexus, which produces the CSF.
Each ventricle lies in contact with five critical neural structures: the caudate nucleus, the thalamus, the fornix, the corpus callosum, and the genu of internal capsule.The authors report their experience in primary tumors of the lateral ventricles of the brain by analysing the symptomatology,the surgical treatment, the complications and the ...
